I ECHANISM FOR HANDLING CARS.

- Patented Ang. S, 1916.

Application filed January 2B, 1907. Serial No. 354,690.

To all whom it may concern Be it known that Sixrfrnnn ALFRED TAY- Lon, a citizen of the United States, residing at `Wilkinsbnrg, in the county of Allegheny and State of Fennsylvania, have invented a new and useful Improvement in Mechanism for Handling Cars, of which improvement the following is a specification. i

The present invention relates to an improved apparatus for dumping coal cars, the primary object being the provision of novel means whereby the contents of the car are discharged in a comparatively progressive stream of constantly varying volume, whereby when the coal falls upon a screen there willbe sufficient agitation to insure the complete removal of all of the slack.

With this and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which vFigure 1 is a side elevation of a coal tipple constructed in accordance with the invention, portions being broken away and shown in section, and the car being shown by full lines in a tilted position and by dotted lines in an upright position. Fig. 2 is a transverse sectional view through the device, showing the swinging track section which is arranged in advance of the tilting platform. Fig. 3 is an enlarged detail view of the ratchet mechanism and cylinder y which are arranged under the tilting track section, portions being broken away and shown in section. Fig. L is an enlarged side elevation showing the pawl and ratchet mechanism as well as the rack and pinion arrangement. Fig. 5 is an enlarged side elevation of the main controlling lever. Fig. 6 is a view showing a modified form of my device as utilized for shifting cars, and Fig. 7 is a plan view of the same.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, the numeral 1 designates a trestle upon which stringers 2 are mounted, the said stringers forming a shaft. yare inclined in such a direction as to slip easily past the pawl 31 when the shaft 18 is support for the track rails 3. A car il of any conventional construction is mounted to travel upon the track, and the said track is formed with a tilting portion 15, and also with a tilting table G upon which the car is pushed prior to discharging the contents thereof. The lower face of the tilting table G is provided with a plate 7 having a socket S formed therein, the said socket receiving a spherical or rounded enlargement 9 at the upper end of a piston 10 which is mounted within an upright cylinder 11. The piston 1() may be provided with a hinged joint 10a so that the upper end thereof can swing laterally in the necessary manner as the tilting table 6 swings up and down. This cylinder 11 is connected by a pipe 13 to a second upright cylinder 12 located under the tilting track section 15, the said cylinders and pipe being filled with some fluid such as water so that when the piston in one cylinder is moved downwardly, the piston in the opposite cylinder will be moved upwardly.

1t may here be noted that the cylinder 12 is shown as having a larger diameter than the cylinder 11 so that a comparatively small movement of the piston therein will produce the necessary movement of the piston l0 of the cylinder 11. The piston 1st which is mounted within the cylinder 12 has an operative connection with the swinging end of the tilting track section 15, and is provide'd upon one side thereof with a rack 1G meshing with a toothed wheel 17 rigid with a horizontal shaft 18 which is disposed transversely with respect to the track and is journaled within brackets 19 projecting from the post 20. A ratchet wheel 30 is also rigidly mounted upon the shaft 1S, the teeth thereof being engaged by a pawl 31 upon a ratchet lever 23 which is loose upon the The teeth of the ratchet wheel 8O rotated by the downward movement of the piston 14, although they engage the said pawl to prevent the upward movement of the said piston.

The end of the ratchet lever 23 is connected by a rod 21 to the lower end of a main lever 22 which is shown as located adjacent the tilting table (3. This main lever 22 is pivotally mounted at an intermediate point in its length upon a frame 2st, and is provided with some conventional form of latch 25 for engagement with a segmental rack 2G formed in connection with the said frame 24.

In the operation of the device, a loaded car moving along the track 3 is first brought upon the tilting track section 15 so as to depress the same. The piston 141 which is connected to the swinging end of the tilting track section 15 is thereby depressed so as to force the fluid from the cylinder 12 to the cylinder 11 and move the piston 10 upwardly so as to bring the tilting table G into an elevated and normal position. As has been previously explained, upon the downward movement of the piston 14; the teeth of the ratchet wheel 30 p`ass freely under the pawl 31 of the ratchet lever 23.

y The car is then moved forward upon the tilting table 6, until the wheels thereof are brought into engagement with suitable abutments the said table 6 being locked against tilting by means of the ratchet wheel 30 which is held against backward movement by means of the pawl 31 of the ratchet lever 23. The operator now grasps the main lever 22 and releasing the latch 25 moves the said lever rearwardly one notch at a time, the said lever 22 being thereby given a'jcrky movement. This jerky movement of the main lever is imparted to the ratchet lever 21 so as to permit a corresponding backward movement of the ratchet wheel 30 and upward movement of the piston 14. This operation is performed so that the piston 1-1 is permitted to rise by a quick succession of short movements, and it will be readily apparent that the piston 10 will drop in a corresponding manner. As this piston H 10 drops, the table 6 will be tilted so as to discharge the contents of the car upon a screen (not shown, but which may be located in the usual position with relation to the car being unloaded). This tiltinglof the table iii the quick succession of jerky movements will jolt the car so that the contents thereof will be agitated and discharged in a stream of varying volume such as will iermit of the coal being effectively screened. his operation is repeated, the lever and ratchet mechanism being reset either by hand or in any other suitable manner.

In Figs. `6 and 7 is shown a modified form of the invention adapted for the shunting or shifting of mine cars, the said device being shown as applied to a coal mine and the cages used therein. A is a track located in the mine, B is the car, while C is a cage adapted to convey the cai from the mine to the tracks D at the top of the shaft E. The said tracks A and D are provided with hinged sections F and Gr, the free ends of which rest respectively upon the pistons I-I and I operating in -the cylinders K and L, the said cylinders being connected by a pipe M. In Fig. 6, the cage in lthe mine contains a loaded car which after being carried to the surface is caused to travel to the iight until it is brought upon the hinged section Gr which is normally held elevated by the piston I. The weight of this car causes said piston I to be forced down into its cylinder so as to force Huid into the 'opposite cylinder K and raise the piston II mounted therein. The hinged section F is thereby elevated so that an empty car thereon will roll down the saine and be brought upon the cage preparatoryvto being again lowered into the line. The loaded car is pushed off section G, unloaded, and brought around a circular or other suitably shaped track to the hinged section F, and the operation repeated.

Having. thus described the invention, what I claim as new and desire to secure by Letters Patent, is

1. In coal car dumping mechanism, a trestle, a track supported thereon, the said track having at the end thereof a tilting table, and a short distance to the rear thereof a hinged section in combination with a pair of communicating cylinders adapted to contain a fluid, the respective pistons of said cylinders being connected Ato the tilting table and the hinged section respectively, and means to enable the piston connected to the tilting table to descend in its cylinder by successive drops.
